Where are all the modded C5 RS6 at? 500awhp to 800awhp+?

[RS6Goals]

Dude. I don't know how skinny your ass is, but mine adds a solid 200+ soaking wet to that 4100, and if you then add a helmet and actually wearing clothes that day at the track, you're easily at 4300-4400....

Oh, I wasnt talking track so I didnt know you were talking about race weight with driver type weigh in.

I'm still waiting for your suggestion btw. Id be happy to consider other options if it will actually be rewarding and not disappointing in the end.

I can think of dozens of other rides out there that you will realize a more rewarding end result for less than this platform.

I don't understand your logic. Whether you're on the street, or on the track, you will always have a driver in the car adding weight to the total package that is being pushed along. Remove the jack, spare tire, and take a good dump before you leave home for othe day and you save a few pounds yes.

Porsche, C7 Audi platform, SRT Grand Cherokee are a trio that pop to mind for AWD. The list opens up for RWD options.

Your efforts would be better directed towards a C7 S6 or better yet an RS7 if you're into the sportback look. What you will spend in time/R&D/buckets of cash chasing this rabbit is readily available for that platform.

If you stick with the C5, tune it to a proven 525-ish hp, keep up on maintenance and enjoy it.

Im not following this logic. Unless im missing something isnt the c7 s6 only rated at 420hp? so even after a chipped RS6, s6 is more money for slower?

and not to be an @$$ but did you really just bring up a RS7 into this, I mean the price difference alone...I don't know about your financial situation but I certainly cannot afford a 100k car

Youtube is your friend

10sec C7 S6 is simple bolt ons and a tune.

10sec C5 RS6 does not exist

all in a 10sec S6 will cost you under 40k

even if you picked up a cheap RS6 for 10k...30k does not get you in the 10s

I find it hard to believe that there's not a single C5 RS6 in the world that runs 10. Either way, I don't know why you're bringing up 1/4 mile times when I kept saying street DD use. All I was asking for was 600whp to start and moving into the 800whp category later down the line. are you telling me this isn't attainable too?

You must have a lot of money to burn to be throwing around a 40k car. I hope you can at least understand that not everyone can just dump an additional 30k in one go. Well at least I cant.

Edit: Suppose to say I can't (drop 30k) not I can.


Does majority in this forum think this way too?

600whp is a stretch. Assuming 15-18% drivetrain loss anyway. 800whp is a waste of time on this platform. Parts are simply too expensive, and labour simply too high - even if you wrench and fab yourself. Yes, you have to account for your own time at some point when it starts to exceed 'maintenance'.

There 'might' be a C5 running a 10sec slip, but it's not on this forum. IF there is one, it's a far cry from normal and includes a host of $$$ to lay claim to doing so.

C7 S6
Can be had on the used market for ~$30k all day
420 hp, APR Stage 2 tuned to 600-ish hp $1.5k




C7 RS7
reaching mid-$50k's
560hp out of the box, APR tuned to 760hp $3k


Let me remind you that you've purchased a used $100k car (adjusted for inflation) for a fraction of the original MSRP. Unfortunately, people quickly forget it still has the maintance cost of that original price.


I know what I have, time & money, in my car over the past 4 years and it's easily reached the entry fee to a C7 S6 and still is nowhere near ready to support the power numbers you're aiming for.


The point being there are better options out there for your goal. Many have come and gone after realizing this. If you're bent on sticking with the C5 take a look at the extensive work done on the RS600 to get to 650whp, maybe reach out to Corbett himself. Somewhere in the instagram comments, AMD mentioned building a second would be quicker but likely cost more. Dig up the old Milka build thread, it's fantastic and a shame he went silent a few years back.

Good luck! Looking forward to anything new on this topic.


To stir the pot a little, I saw these on rs246 a while back.

I've probably seen 4-5 of similar threads / aspirations in my brief time here, and no slight to the OP or his ambitions.... just observing..... but I seem to recall the 4-5 previous went from being all about it and totally talking it up, researching and math and blueprints and plans etc.... and some I think actually tried to get started... but then not only seemed to throw in the towel (or their busted bank account) in relatively short order, but then totally disappeared from the forum altogether. Like dreaming hard and vocally to totally turning to ghost vapor in the matter of a few months. Good luck though. If your trans is good and you're limited budget as you say, you might as well sell it now while its worth something before you blow it up bc you will.

This is all well and good but again why is this even still being discussed after I said that its out of the budget. Im trying to build things on the low and you guys are recommending a path that would triple the price.(you're talking about entry price too)

Dont get me wrong if I can drop 30k now ill seriously consider those options you guys are suggesting.

BTW what did you mean by "maintance cost of that original price"? This is new to me. Car is a car and the most part its pretty much all the same. Some just needs less maintenance.

[RS6Goals]

Well, Thanks for all the feedback guys. This has been informative, I definitely found out some things to watch out for and found out some great info.

Ill start a build thread when I start planning that 550-600whp

[RS6Goals]

I only talk about without driver because it's more consistent. Driver weight and gear vary. But a lot...


And Cherokee is out it's an SUV. Not to mention it's 4700... I'd be slower how is that any better as a base.
C7 can you be a bit specific? And pretty sure it's going to be pricey.
And I'm pretty sure any porsche that's worth discussing will be way too expensive.

You could always go this route: https://blog.1aauto.com/2003-audi-rs6-ls1-engine-swap/

In all seriousness, one of these "big hp" threads from a new owner pop up on a semi-regular basis so we're all a bit salty. I'd honestly love to see someone mod the hell out of one of these cars but to my knowledge it hasn't been done yet because of what everyone here is saying. If you do attempt it, please post a bunch of pics. It would be fun to watch!

I saw that before on ls1tech. I had consider it since I'm pretty familiar with LS but the car is fully functional so to me it doesn't make sense.

And yea I notice that, I couldn't tell if it's purist mentality or something else. And I'll try not to disappoint.

On a side note what do you guys use to data log? Looking to make some comparison.

+1. It's my observations having worked on three different cars in varying levels of capacity that the challenge isn't the hand assembled Cosworth engine. It's the physical volume limitations. MOST owners will not go to insane levels of modification to adjust the physical parameters of the compartment, or the configuration of the engine and it's components. At least not owners that drive this car. Yes this car is the Devil in sheep's clothing and an Autobahn speedboat, but it's far from a track star.

I can easily modify the power output in my turbo Buick by running different turbo(s), along with other bolt-ons. I can also go to the extremes of fabricating something insane and still be further ahead because at least I had space....

If you don't already own a C5 RS6, then I think you first need to take a look at the space limitations before you pour your heart and sole in to thinking this is the route you wish to go. Long time members have all heard and seen the same optimism and excitement time over again and again.
